Way back on August 18, 1920, the 19th Amendment became official when the Tennessee general assembly ratified it. That vote tipped the number to 36 states in favor, a 3/4th majority. The legend goes it was a Tennessee lawmaker’s mother who urged her son to be a “good boy” and vote in favor of the amendment, and apparently he did, breaking a tie vote.
The fight began much earlier back in 1848 at Seneca Falls at the women’s rights convention when the call was made for equal rights for women but it was 72 years before it would become law.
So the lessons of the day are: Ladies, value your vote and, gents, listen to your mothers.
